Here’s the nutshell: Start with 0.025% if you’re new, have sensitive skin, or are over 50 (older skin can atrophy, so go easy). Graduate to 0.05% after 3–6 months if you want faster results on moderate wrinkles. Only touch 0.1% if you’re a seasoned user with tough skin and deep lines that don’t budge.
And always—I mean always—use sunscreen. Tretinoin makes your skin a magnet for UV damage. You do not want to trade wrinkles for sunspots. That’s like dodging a pie and walking into a brick wall.
One last coffee chat tip
Don’t compare yourself to the Instagram influencer who uses 0.1% and claims to have zero irritation. They’re lying, or they’re secretly using a barrier-repair routine that costs more than your rent.
Your skin, your pace. Start low, go slow, and let the tretinoin do its slow-burn magic. Wrinkles took years to show up—they won’t leave in a week. But with the right strength, you’ll wake up one day and think, “Huh. I look like me, but brighter.”
And honestly? That’s the whole point. Now go forth, and may your moisturizer be endless.
